I absolutely loathe and detest the word "App". Whenever anybody says it I die a little bit inside. It's very similar to how I used to feel about the term "Web 2.0". Apps are just the current fad. I'm constantly bombarded by articles about some asshole or other who made a million dollars by publishing some bullshit "App" in the "App Store".
App is just short for Application, which has been in the computer lexicon for decades. It's pretty much just another way of saying "Program", or "Piece of Software". Whenever someone approaches me by saying "I had a great idea for an App..." I scream in my head at them and fight back the impulse for murder. Now, if someone approached me and said "I had a great idea for a program..." I'd actually take them seriously.
I think my issue with App is that it's this bullshit yuppie slang invented by "App"le. I mean seriously, I understand that the word Application is pretty long and could be shortened. But Apple's created this whole concept. Not only have they shortened the word Application, but they've shortened the whole program. Now it's just a fancy little icon that you pay $0.99 for that does fuck all once you've put it on the phone. They're mostly good for wasting time while you're taking a dump.
Now every prick in line for a latte at Starbucks thinks they can make a million dollars by spending $3000 hiring Indians to write code and then unleash their horseshit on everybody who has a smart phone, which is everyone.
And just like that, Apple commoditized, yuppified, and took all of the remaining dignity out of programming as a profession.
